FIDJI 2003 was an international forum for researchers and practitioners in- rested in the advances in, and applications of, software engineering for distri- ted applicationdevelopment. Concerningthe technologies,the workshopfocused on “Java-related” technologies. It was an opportunity to present and observe the latest research, results, and ideas in these areas.

We selected, for these post-workshop proceedings, 14 papers, amongst 29 submitted, two tutorials, and one keynote talk. FIDJI2003aimedatpromotingascienti?capproachtosoftwareengineering. The scope of the workshop included the following topics: – design of distributed Java applications – Java-related technologies – software and system architecture engineering and development methodo- gies – development methodologies for UML – development methodologies for reliable distributed systems – component-based development methodologies – managementofevolutions/iterationsintheanalysis,design,implementation, and test phases – dependability support during system life-cycles – managing inconsistencies during application development – atomicity and exception handling in system development – software architectures, frameworks, and design patterns for developing d- tributed systems – integration of formal techniques in the development process – formal analysis and grounding of modeling notation and techniques (e. g. , UML, metamodeling) – supporting the security requirements of distributed applications in the - velopment process – refactoring methods – industrial and academic case studies – development and analysis tools Theorganization of such a workshop represents an important amount of work.
